Is sugar making you go bald?

My google alerts, alerted me to this clip from The Doctors that says sugar is the surprising food behind your hair loss. While absolutely being sensationalist I do have to give them a little credit for not going full Dr Oz. They made sure to state that sugar, in and of itself, is not inherently evil and that it’s fine to consume it in small quantities. According to them, sugar is leading to expanding waistlines and thinning hairlines. Sweet.

It’s a very short clip, and naturally, there aren’t any references. As far as I can tell, there hasn’t been any new research in this area. I found a few studies from about a decade ago looking at the connection between an alleged male form of PCOS (polycystic ovary syndrome) and premature balding and insulin resistance (1, 2). These studies did not explicitly examine a link between sugar consumption and hair loss.

Insulin resistance is an impaired ability of the body to properly use insulin. The causes of insulin resistance are not yet fully known; however, major contributing factors include diet and lifestyle. High levels of fat around the waist and a sedentary lifestyle may both contribute to insulin resistance. Excessive consumption of sugar and refined carbohydrates may contribute to those high levels of abdominal adiposity. However, excessive consumption of calories in general, regardless of source, may cause accumulation of excessive abdominal fat.

There are many causes of hair loss, including hormonal disruptions. These may go hand-in-hand with insulin resistance and conditions such as PCOS and type 2 diabetes.

To summarize: The Doctors have taken the leap from excessive sugar consumption to hair loss. There are many other factors at play and sugar itself would not be the direct cause of hair loss, even if it is a contributing factor in the development of hormonal disruptions. Because there are many other causes of hair loss, before you go sugar-free, you should book an appointment with your primary health care provider to obtain an accurate diagnosis. That being said, if you watched that video and thought “I’m eating too much sugar” there’s absolutely no harm in cutting back. Too much of anything is bad for you.
